Superoxide dismutase (SOD) is the first line of defense against oxidative stress induced by endogenous and/or exogenous factors and thus helps in maintaining the cellular integrity. Its activity is related to many diseases; so, it is of importance to study the structure and expression of SOD gene in an animal naturally exposed most of its life to the direct sunlight as a cause of oxidative stre...

Mitochondrial DNA (mtDNA) deletion mutations are proposed contributors to aging-related muscle fiber loss and atrophy, but evidence of a causal role for these mutations in muscle aging is lacking. Elucidating the etiology of in vivo mtDNA deletion mutations will help to better understand and test the possible roles of these mutations in aging. The implication of mtDNA mutations in aging is base...

زمینه و هدف: کم‌تحرکی در مقابل آن تمرین جزء عوامل مرتبط با شاخص‌های آسیب کبدی به‌شمار می‌روند. وجود این هنوز نقش بسیاری از تمرین‌های ورزشی به‌ویژه تمرینات تناوبی مقاومتی مصرف برخی مکمل‌های غذایی جمله اسپیرولینا بر ایمنی التهابی کاملاٌ شناخته نشده است؛ بنابراین هدف پژوهش تعیین اثر هشت هفته مکمل‌دهی هوازی فعالیت بافت کبد بیان ژن CXCL1 عضلة موش‌های صحرایی نر بود.مواد روش‌ها: نیمه‌تجربی، 60 سر موش ن...

An eight-week trial was conducted to investigate the effects of sanguinarine supplementation (600 μg and 1200 μg/kg) in high-fat (crude fat: 10%) diets (HF) on intestinal physiological function Ctenopharyngodon idellus (initial weight 50.21 ± 0.68 g), based a basic diet (5% crude fat, CON), which were named HFLS HFHS, respectively. The results showed that HF significantly impaired immune physic...

Two euryhaline rotifers, the temperate species Brachionus plicatilis and tropical rotundiformis , were used to investigate effects of iron (FeSO 4 ·7H 2 O), an essential trace metal, on reproductive patterns lifetables, including metabolism lipid reactive oxygen (ROS). B. was more sensitive with regard sexual reproduction. While had no significant effect population growth at 0–48 μg/mL, it caus...

The carotid body (CB) is a peripheral chemoreceptor organ that contains clusters of electrically excitable secretory cells, the glomus cells, which express several types of membrane ion channels that influence its excitability. These cells act as sensors or chemotransducers, detecting different chemical stimuli and triggering an action potential in the afferent fibres that lie in synaptic appos...

This research evaluated the protective effect of vitamin A (VA) on adverse fish oil (FO) substitution with palm (PO) in an economical crab Eriocheir sinensis. Three diets FO, PO, and PO + 8000 IU / kg VA as main lipid sources were fed to crab...
